Unit 10 -1
Discussion
The cloud computing system shares the common characteristics of the general security attacks to all types of distributed computing systems, such as the following (Prakash & Darbari, 2012):
· Eavesdropping (gaining secret information)
· Masquerading (making assumptions on the identity of users)
· Message tampering (changing the content of the message)
· Replaying the message
· Denial of services
However, because of several special system features of the cloud computing systems, such as virtual machines (VM), trust asymmetry, semitransparent system architecture, and so forth, the cloud computing system has a few special security issues. These are summarized into the following 10 technical aspects (Sakr & Gaber, 2014):
· Exploitation of co-tenancy
· Secure architecture for the cloud
· Accountability for outsourced data
· Confidentiality of data and computation
· Privacy
· Verifying outsourced computation
· Verifying capability
· Cloud forensics
· Misuse detection
· Resource accounting and economic attacks
Additionally, even some non-technical areas (e.g., regulatory compliance legal jurisdiction) and many security researches’ assumptions pose security challenges to which no meaningful solutions have yet been made (Prakash & Darbari, 2012). All of these have kept security in cloud computing systems a current and hot research subject.
Complete the reading assignment, and search the Library and Internet to find and study more references that discuss the security issues of cloud computing systems and how to solve them. Based on the results of your research, discuss the following tasks:
· Identify 2 security issues associated with cloud computing system.
· What are the root causes of these 2 security issues?
· How can these 2 security issues be solved?
Justify your point of view and provide examples, as necessary.
Discussion 2
Throughout this class, you have touched many current hot research subjects in big data analytics. You are familiar with some of problems that are still waiting for a better solution in big data analytics. Assume that you will write a research paper on a big data analytic related subject. Discuss the following:
· Present your paper’s title, the motivation in maximum 3 sentences, the problem statement in 1 sentence, and the hypothesis statement in 1 sentence.
· The hypothesis statement will include a proposed solution to address the root cause of the problem presented in your problem statement.
· Present 2 research questions, and discuss your thought process on how you came up with your research questions based on the motivations, the problem statement, and the hypothesis statement.
· Use 1 sentence to specify the new contribution made to the body of knowledge by your proposed solution.
